V-Sagat is prolly one of the easiest V-ism characters to get used to. His VC’s are very easy and are also easy to modify during VC if someone is falling in a way you didnt expect.
jumping SK is such a sneaky crossup. But most of the time youll be trying to poke with crouching fierce. If someone starts beating the fierce then the crouching strong has slightly higher priority.
standing FK has a bit of lag attached to it so dont be predictable with it.
for antiair I usually do standing JP into JP tiger uppercut.
Otherwise everything else posted here is good.
